Dances should have several adult chaperones in attendance.
This is a great option for parents or chaperones who may be visiting with children but aren't themselves interested in every ride.
Parents and chaperones were often there more to reinforce a sense of responsibility for the commitment between the parties rather than actually preventing any activities.
Make sure that all of your travel arrangements, registration, chaperones and other details are in place.
For students traveling in the United States - Chaperones can be covered if they account for less than 20% of the group members.
